How much did you make exactly? That's an extremely disciplined approach. I'd assume you could do pretty well at other stuff if you took it as serious as you did your online poker
Your story reminded me of a case I personally know of a guy who was a very disciplined poker player for a period of time and one day won a sweet €90000 prize in an online tournament after a lot of effort. Apart from poker, his life was a mess (living with his mother, no even a driving licence, no serious job). He spent the whole amount on partying, hotels and cocaine. He never got again any substantial money from poker and his life is still a mess last time I knew.
I don’t know how long he played, he certainly didn’t mention a grind as described here.
But, he netted enough to buy his then new $30k Lexus.
A lucrative hobby if nothing else.
